The nucleic acid sampling tube placing cabin according to claim 2, wherein guide grooves are formed in the left side and the right side of the rack, the guide grooves are respectively installed in a matched manner with the guide rail, so that the rack is installed on the guide rail in a sliding manner, a row of straight teeth are arranged at the bottom of the rack, the rack is installed in a mutually meshed manner through the straight teeth distributed at the bottom and the gear, and the front end of the rack is fixedly connected with the side surface of the side plate in the placing cabin.

6. The nucleic acid sampling tube placing cabin according to claim 1, wherein the gear is arranged at one side of the inside of the outer side frame close to the placing cabin body, a gear shaft of the gear is rotationally connected with the inner wall of the outer side frame, the gear is a straight toothed spur gear, and the gear is used for converting the rotation motion of the gear into the linear motion of the rack.

7. The nucleic acid sampling tube placing cabin according to claim 1, wherein when the gear is driven by a motor to rotate in the forward direction, the gear drives the rack to move forward along the guide rail, and the placing cabin body moves forward together under the pushing of the rack; when the gear rotates reversely under the driving of the motor, the gear drives the rack to move backwards along the guide rail, and the placing cabin body moves backwards together under the pulling of the rack.

8. A nucleic acid sampling box, which is characterized by comprising a box body, and a test tube ejection cabin and a sample recovery cabin which are arranged in the box body, wherein the test tube ejection cabin and the sample recovery cabin are both in the structure of a nucleic acid sampling tube placing cabin as claimed in any one of claims 1 to 7, and the nucleic acid sampling box is arranged on a chassis of a vehicle.

9. The nucleic acid sampling box according to claim 8, wherein a cotton swab storage bin, a first linear guide rail and a second linear guide rail are further installed in the nucleic acid sampling box, and clamps are arranged on the first linear guide rail and the second linear guide rail.

10. The nucleic acid sampling box according to claim 9, wherein after the first linear guide control clamp puts the nucleic acid reagent tube into the test tube ejection chamber, the test tube ejection chamber is pushed forward by a linear motion mechanism behind the test tube ejection chamber, so that the test tube ejection chamber is pushed out of the box body;

after the nucleic acid sampling box is used for self-service nucleic acid sampling, the sample recovery cabin is automatically pushed out of the box body by using the linear motion mechanism behind the sample recovery cabin, and after the sample recovery cabin senses that a sample reagent tube is put in, the sample recovery cabin is pulled backwards by using the linear motion mechanism behind the sample recovery cabin, so that the sample recovery cabin is recovered into the box body.
